When my propane furnace died a couple of winters ago I thought about the cost of propane ( about 750 to 8- hundred dollars to fill the tank), the cost of a new furnace for a mobile home ( about 12-hundred dollars), and the cost of instillation. Those thoughts kept me cold for a couple of years.
After looking at alternatives, I decided that the modern wood stove was the ticket for me.
I am not disappointed. The essential cost was about the same as going propane but the wood goes a lot further for the dollar than propane.
